Naruto, One Piece, Detective Conan, really anything over 500 needs to die already. I know One Piece has a great story but really time skip was the half way point by that logic I'll be 32 or so when it ends... pretty sure Oda is gonna kick the bucket before he finishes it. Oh also reason I didn't put Bleach is just that's a guilty pleasure I indulge in also Medaka Box. Haven't followed since the start but it should have finished when Zenkichi won.
